I recently bought the Hock spokeshave kit and the instructions call for assembling the tool with the brass plate and then shaping it on the bandsaw which means cutting through the brass. See this video at the 6:25 point:

Most brass is pretty soft and I think you’ll get along fine with your bandsaw using a 10 TPI or finer blade. I have sawed many miles of brass with jeweler’s saws and it is not hard on blades at all so you could use a fret saw or jewelers saw instead of your BS.
